SPECIFICATION forming'part of Letters Patent No. 614,578, dated November 22, 1898.

Application led March 28 1 8 9 8 To a/ZZ whom it may con/cern:

Be it known that we, HERMAN G.` RICH, residing at Des Moines, Polk county, and JOHN A. CHANDLER and WILLIAM H. DUNsHEE, re-

siding at Cedar Rapids, in the county of Linn, State of Iowa, citizens of the United States, have invented certain new and useful Improvements in Filters; and `we do hereby declare the following to be a full, clear, and eX- Io act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a simple and eflicient filter and water-cooler for use in residences, oflices, places of public resort, and the like.

The invention consists in the construction, combination, and arrangement of parts, as hereinafter fully set forth and claimed, ref- 2o erence being had to the accompanying drawings, in which- Figure l is a view in perspective of the device embodying our invention with the lid up, showing water and ice therein. Fig. 2, Sheet 2 5 2, is a front elevation of the same. Fig. 3 is a top view of the same. Fig. I, Sheet 3, is a sectional view of the same in a vertical plane in the line fr fo of Fig. 3.

Similar letters of reference indicate correspondingparts.

Referring to the drawings, A designates a tank, preferably of wood and suitably lined with zinc or like non oxidizable material A. In practice this tank is made of suitable 3 5 size to set on a table, stand, or bracket and isprovided with a suitable hin-ged lid A2, constituting a part of the top or cover thereof. To the other portion of the cover A3 the operative parts of the lter hereinafter to be 4o described are attached. Suitable provision is mads for providing the sides of the tank with some non-conducting material, such as asbestos; but as this relates to'detail of manufacture according to well-known methods it has not been thought necessary to illustrate it herein.

A part of the cover of the tank is securely attached to the upper edgethereof, and to this cover, near the back side of the tank, is

5o secured a pu1np-cylinderB. In practice the Serial No. 675,515. (No model.)

upper end of this cylinder is threaded down from the top far enough to take a jam-nut B below the board forming this portion of the tank-cover, and the upper cylinder or head B2 is screwed down tightly on the upper side 55 of said board, making a tight joint, as will be seen by reference to Fig. 4. The lower cap BS communicates by a pipe C with an airchamber D and is provided near the bottom of the tank with two check-valves E E both 6o of which of course open inwardly-t t is to say, to allow the water to iiow to th left, as the same is illustrated in said figure. In-the pump-cylinder is iitted a suitable piston B5, connecting by its stem BG with a hand-lever 65 F, connecting by a link F with a suitable pivot-plate F2, attached to this p'rt of the tank-cover back of the pump. he` other end of the lever terminates in a handle F3, which for convenience is turned downwardly, 7o as shown.

In practice the air-chamber is made in the ellipsoidal form shown, the lower end being practically as large as the upper end to near the neck, which connects with the horizontal pipes near the bottom of the tank. The object of this is to give the greatest possible capacity to the air-chamber within the comparatively small space occupied by the operative parts of the filter. One side of the 8o outlet of the air-chamber communicates by an upright pipe with the shell of a filter G. This is. preferably cylindrical and is closed by a permanent head G'. At the upper end this cylinder is flanged outwardly at G2, and the iiange rests in a suitable recess formed in the upper part of the board permanently attached tothe top of the tank. Vithin this shell is placed the filter proper, G3, which in practice is a cylindrical body of porous stone 9o somewhat smaller than the interior of the cylinder and provided with a hole lengthwise through the center thereof. To the ends of this filter-stone are attached a pair of heads G4 and G5, connected by a screw-threaded rod 95 G6, screwing into suitable bosses on the heads referred to. Outside of these bosses and between the filter-cylinder and the shell containing it are placed cupped gaskets G7,w h1ch fit nicely between the'lter-stone and the Io@ heads adjacent to each end. An air-tight space is thus made surrounding the body of the filter and between it and the shell, in which space the water is discharged from the pump above described. Such water under the pressure exerted by the force-pump passes through the body of the filter-stone into the central orifice and escapes thence into a nozzle G8, connecting with the upper head of the filter through small waterways formed in the downwardly-projecting boss of this head G9. The nozzle is provided with a suitable stopcock G1". p

This construction of the lter is such as to admit of the filter proper being entirely and very quickly removed from the shell inclosing it, as may be necessary in cleaning itfrom time to time.

Under the overhanging end of the nozzle G10 is placed a small shelf II, resting on suitable brackets Il', attached to the side of the tank, affording a convenient resting-place for pitcher, glass, or other water vessel.

The filter apparatus is designed to occupy acomparatively small portion of the interior space of the tank and is preferably placed at one side, as indicated in the drawings. The remainder of the tank affords room for a considerable body of -water and ice, as appears by reference to Fig. l.

The operation of the device is so simple as to require little explanation. It is evident that by working the hand-lever in theV ordinary way water from the tank will be drawn into the pipe throughthe right-hand checkvalve and thence forced into the annular receptacle, between the filter-stone and the filter-shell. through the filter-stone into the central hole ready to be discharged on opening the stopcock G10. The purpose of the air-chamber is of course to give a steady ow to the stream issuing from the nozzle or bib. It will be evident also that this air-pressure acts continuously even after the cessation of pumping, thus always keeping the central part of the filter full of water ready to be discharged on opening the bib. It is thus not always necessary for the operator to pump` in order to obtain a drink of water, though of course but a limited amount of water will fiow out unless the pump is used.

It will be evident that the air-chamber might be dispensed with but in such case the water from the bib would fiow intermittently and only in response to movement of the pump-lever.

A special purpose aside from the conven ience in detaching the filter, as already described, in attaching the parts to the tankcover is to avoid the possibility of leakage incident to the fastening of any parts to the bottom of the tank.

The device is intended to take the place of the ordinary water-cooler and serve the same purpose of supplying a cool refreshing draft This water is gradually forced and also to secure the further advantage of rendering the water perfectly pure and wholesome by ltration.

The position of the filter inside the tank and wholly or partly submerged in ice-water is such as to keep the water issuing from it cold at all times. `This is a very desirable feature as compared with apparatus in which the filter is exposed to the air, giving forth lukewarm water in hot weather.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, ist l. In a filter, the combination with a tank adapted to hold ice-water, and having a cover partly fixed to said tank, a force-pump cylinder attached to said fixed cover, an air-chamber adjacent thereto, and a filter attached to said cover, suitable pipe communicating with the filter, air-chamber and pump, and suitable check-valves, substantially as and for the purpose set forth. i 2. In a filter, the combination with a receptacle for ice and water, of a force-pump attached to a Xed portion of said tank-cover, a detachable filter mounted in said cover, a water-pipe communicating with thepump and filter, and suitable check-valves, substantially as and for the purpose set forth.
